Multi-Domain Information Exposure using ALTO: The Good, the Bad and the Solution

Multi-domain applications can benefit from network information exposure using the ALTO protocol framework. ALTO provides network state and capabilities to applications to be more flexible in terms of rate adaptation, transmission time, and server/path selection. However, different key issues arise when designing an ALTO solution for multi-domain environments. In this talk, we summarize such issues along with basic mechanisms to be considered to allow ALTO to expose network information across multiple domains.
